In the Layer State drop-down list, choose New Layer State.
In the New Layer State to Save dialog box, enter a name for the new layer state, or choose a name from the list. You can also add a description. Click OK.
Click Close.
Note:
Normally, you do not need to click the Save button. Save overwrites the currently selected layer state with the current layer settings, and saves the list of properties that are checked or unchecked by default.
The Layer States Manager is also accessible from the Layer Properties Manager.
